Thanks. I do use various references, but usually real world examples to try to study how things look. I rarely reference specific artists. It varies, but for the ideas I often just smash a couple things I want to draw and see if I can come up with something interesting. In this case I wanted to include a music instrument in some manner( because of in game story reasons) and I wanted to paint some environmental art. Eventually I came up with this image.
I also have just a list of ideas I want to work on sooner or later. This sort of artwork takes a while to make, so I often come up with stuff that I keep on the backburner until it spends enough time in my head to develop into something I want to make or until I forget about it. Hope that makes sense
